Below is a link to the respirator filters i have, good for acid vapors ect, not sure what kind of gas vapors welding creates or what might be created if i weld over any chemicals like Phosphoric acid ect. Do you think i should be good? http://solutions.3m.com/wps/portal/3...294936907&rt=d

Re: Rat repair.
Get the media blaster out and kill that rust and cut out the rot. Sky had to do both right side doors on my truck inner and outer about 10" up.

Re: Rat repair.
Nah! Not time to get nervous. For me, I just figure if I screw it up, cut the door a little higher than last time and start over with a new patch - first try turned out to be practice. I brought up the seam sealer because I'm pretty sure my 78 had it there, which if yours did would likely keep rust converter from getting in there very well.

Re: Rat repair.
First thing i did was scribe my 8" measurement across the door so i didn't loose it, it was just marked with a sharpie.
Keeping with that video's recommendation of cutting a slight angle I measured down 1" and 1 1/4" below my 8" mark and cut about 3 more inches off the skin, the skin still had some rust on the back side, but the remaining skin has no more rust per flashlight and mirror inspection. However there is still a bit of rust in the seam area. what do ya think, go ahead and go above the body line? I will still coat the inside with the stuff Vic recommended. I gotta concentrate on not cutting past the skin depth a little better LOL! ![]()

Re: Rat repair.
It might be easer to replace the door skin and the left inner bottom corner with new panel patches. Then you can media blast the rust inside the door paint to preserve the rest.

Your patch is going to be tricky but if you go slow and keep the heat down, it's do-able. If it turns into a goat rodeo, you can always skin it like DWilbur suggested. Keep up the good work!

Re: Rat repair.
![]() If you have any question, wear the respirator. Welding heat will vaporize alot of things, some don't really bother. The arc can have an odd effect on stuff and the uv can spice stuff up too. Best to be safe. I do a lot of breath holding when I weld. Good luck with the repair! |

And that Goat Rodeo had been my biggest fear on these doors, If there is a better way to cut the skin i'm all ears, but at least the weld being higher up i can reach in with a dolly and do some planishing.

Re: Rat repair.
So nothing much done this morning but a little thinking ect.. Had to run across town and killed my morning.
The doors are suppose to have a compound curve so front to back is about 1/4 to 3/8" higher in the middle than it is front and back, i posted earlier about how the upper skin popped inward when i made my first cut, i just put a straight edge on it and its pretty much flat until it gets to the front and back edges.. Trying to figure out how i could possibly get the remaining skin to curve out a little before i try and weld in my patch, if i pull it its tight so no oil canning. Would slow and careful shot blasting the outter skin stretchit enough to raise the skin to make that contour or would that just be a waste of time? I did notice both of my doors don't ( or didn't ) have a true contour front to back at the body line, the back half is convex, the front half is concave.

Re: Rat repair.
Sorry no picture on this one.. can get later if someone needs to look.
I started working on the door again Monday I roughed the repair panel down close to the body line and the first thing i noticed is the repair panel folds (at 90 deg) are about 3/16 wider than the folds on the stock door skin, i know the folds on the door skin are slightly wider than the inner shell. If i fold the repair panel at the existing fold then it will end up being too wide, do you body guys actually use a hammer and dolly to bump that fold in further to match the existing skin?

Re: Rat repair.
So being as i didn't buy lower inner's for the doors i went to work on the lower corner, i cut the rust back a bit and wire brushed, then i had to figure out how to shape the end of the triangle, i got a piece of wood and my little wood router and did a rough triangle the same size as the door, then i hammered out a patch panel and welded it in.
Then i took the rest of the paint off the bottom of the door and treated the remaining rust.

Re: Rat repair.
Now for the bad news... I was working yesterday and noticed a little splatter that looked like it could have been moisture coming thru my dremel on my work bench, i had to leave for work so i drained the water trap on the manifold and left, today i was working and i realized that that splatter is still there and its worse!
Further investigation made my heart sink, my life time investment has a blown shaft seal... I didn't find it yesterday because it was the back side of the compressor... Guess i need to call Quincy tomorrow to figure out what to do, this was a purchase through Lowes that i didn't bother with the Lowes extended warrenty plan, now i wish i would have! Sometimes ya just want to give up.....

Re: Rat repair.
I'm assuming Quincy will cover it under warranty. Still, it sucks after all the research you did plus the $$$.
As for the cleanup, I use solvent for messes like this. The stuff I buy is hard to find (Hangsterfer's Ozonic 117) but any Varsol type product would work equally well. You can also get Wax and Grease remover from most places that sell paint and body supplies. Usually available in quarts or gallons. For homemade wax and grease remover, mix one third isopropyl alcohol, one third acetone and one third water. Works great and the components are readily available.

Re: Rat repair.
That is not good news on the compressor, but like most new things a little tweak/repair and it'll be good to go for a long time. Pressure gauge biffed it on our new compressor immediately. Couldn't wait for the replacement to get here so now I've got a spare.
Your rust repair work is progressing very nicely, keep up the good work!

I had to make room for the service tech so today my redneck car cover came down and the truck went back under the 10X20 cover, but not before i took the truck for a ride around the block with out the door on it, needed a cheap thrill i guess.
